In the following diagram, it is known that EHG is a right angle, m EHF x 1 and m GHF x 5 5.
Find the value of x, the numerical values of m EHF m GHF and , and mark them on the diagram
Answer:
Step-by-step explanation:
From the diagram, it can be seen that m EHF+ m GHF = mEHG
mEHG is a right angle, then mEHG = 90°
Given
m EHF = x
m GHF = 5x
Substituting the given parameters into the formula to get x;
x+5x= 90
6x = 90
Divide both sides by 6;
6x/6 = 90/6
x = 15
Hence the value of x is 15°
Since m EHF = x, therefore the numerical value of m EHF is 15°.
Also since m GHF = 5x, the numerical value of m GHF = 5(15) = 75°

Two identical pumps fill a water reservoir in 10 hours. How many additional pumps should be turned on if the reservoir must be willed in 4 hours?
Answer:
5
Step-by-step explanation:
All you have to do is 2*10=20 and then 20/4=5
So 5 additional pumps should be turned on.
The number of additional pumps that should be turned on if the reservoir must be filled in 4 hours is 3 pumps
Given:
2 identical pumps = 10 hours
Time taken for each pump = Total time ÷ number of pumps
= 10 hours / 2 pumps
= 5 hours per pump
Total hours to fill a reservoir = 4 hours
let
x = number of pumps
Number of pumps = (Time taken for each pump × Total hours to fill a reservoir) / Total hours to fill a reservoir
= (5 × 4) / 4
= 20 / 4
= 5 pumps
Additional pump needed = Pumps needed - available pumps
= 5 - 2
= 3
Therefore, number of additional pumps that should be turned on if the reservoir must be filled in 4 hours is 3

Answer:
- 2, - 4, - 6, -8
Step-by-step explanation:
If the first term of the arithmetic sequence is is -2 , and the common difference is -2, then we can generate the first four terms the following way:
a1 = - 2
a2 = - 2 - 2 = - 4
a3 = - 4 - 2 = - 6

1. Given right triangle ABC with the right angle C and sin A = 1/3, which is of the following expression is also equal to 1/3?
A. cos B
B. cos(90° - A)
C. sin(90°- B)
D. Both A and B
2. The maximum slope for a hand propelled wheel chair ramp should be a 1-inch rise to every 12 inch of length. What is that maximum ramp angle recommended to the nearest degree?
Answer:
1) B
2) About 5°.
Step-by-step explanation:
1)
We can use the following co-function identity:
[tex]\sin(\theta)=\cos(90-\theta)[/tex]
Substitute A for θ:
[tex]\sin(A)=\cos(90-A)[/tex]
Since we know that sin(A) is 1/3, this means that cos(90-A) must also be 1/3.
So, our answer is B.
2)
Refer to the drawing.
Remember that 1-inch rise is a height of 1 while a 12 inch length is a length of 12.
So, to find the maximum ramp angle, we simply need to find the value of x.
We know the sides opposite and adjacent to x. So, we can use tangent:
[tex]\tan(x)=\text{opp}/\text{adj}[/tex]
Substitute 1 for the opposite side and 12 for the adjacent side:
[tex]\tan(x)=1/12[/tex]
Take the inverse tangent of both sides:
[tex]x=\tan^{-1}(1/12)[/tex]
Use a calculator. Make sure you're in Degrees mode:
[tex]x\approx4.76\textdegree\approx5\textdegree[/tex]
So, the maximum ramp angle should be about 5°

Find x and y (round to the nearest tenths is needed)
Picture below.. help
Answer:
x=11/2
y=11√3/2
Step-by-step explanation:
This is a 30°-60°-90° triangle. So if we call the short side x, then the 2nd longest side will be x√(3), and the hypotenuse is 2x.
So here we have 11 as the hypotenuse. So:
11=2x ---> x=11/2 and y=x√3=11√3/2
You could also just take the sine and cosine of the sides using either angle as well. But this is a common ration of sides that is talked about in Math classes; especially Trig.
Edit: I missed the part where you said you wanted rounded answers. Just plug the values into a calculator and round as needed.

what is the distance between -4 and 8 on a number line
Answer:
12
Step-by-step explanation:
you can hop 12 times to the right
The distance between -4 and 8 on a number line is 12.
To find the distance between -4 and 8 on a number line, you can subtract the smaller number from the larger number. In this case:
Distance = |8 - (-4)|
To subtract a negative number, you can think of it as adding the absolute value of that negative number:
Distance = |8 + 4|
Now, perform the addition:
Distance = |12|
The absolute value of 12 is 12, so the distance between -4 and 8 on a number line is 12 units.
Hence, the distance between -4 and 8 on a number line is 12.
